Auto Snapshot is a very basic Wordpress plugin that works alongsite the WPMUDEV Snapshot Pro Plugin.
It only works on multisite installations and it allows you to automatically add a snapshot whenever a site is created, this should reduce admin overheads on multisite installations a fair bit.
This isn't in any way affiliated with WPMUDEV and was born out of my need to automate this task.
Upload this file to your wp-content/plugins directory inside a auto-snapshot directory. Therefore the full path should be wp-content/plugins/auto-snapshot.
From there, you can activate it as usual and it will kick in as long as you've got Snapshot Pro installed.
The settings are currently hardcoded into the plugin but maybe one day I will update this to allow you to set them.
In the meantime you can open up auto-snapshot.php and play with the settings array on line 70
It's currently set to backup all files and database tables locally as that's what I need.
If you want to contribute to this, please do. Make a PR or create an issue. If I have time I'll do what I can with it.
